The Emerald 9250 Digital Delay Pulse Generator

By Quantum Composers, Inc

The Emerald 9250 series pulse generator was designed to meet the growing demand for an affordable yet high resolution system synchronizer. This precision delay generator comes standard with a 280 ppb TCXO oscillator and 5ps timing resolution for high performance in a compact packaging. - 4 Independent Channel Outputs - 5 ps Delay Resolution - TCXO 280 ppb oscillator - < 15 ps RMS Jitter - "Virtual" Channel Timers - Fast Rise Time, < 2 ns - 8 Independent Pulses (width & delay) with the virtual timers - Up to 20MHz External Trigger Rate - Wireless Option Via Bluetooth - Full Customer Support The Emerald uses an included custom software application as the primary means of communication. The software allows simplified control of the unit via USB or optional wireless, enabling the user to create complex pulse trains and save them for future recall. The software also allows users to manually input SCPI (Standard Commands for Programmable Instruments) based commands via the Command Terminal Section. The 9250 will feature a unique Bluetooth wireless option. This allows the pulse generator to communicate with Bluetooth enabled devices such as laptops, tablets, or smartphones. The included GUI software can be paired with the Bluetooth device to program or control the instrument wirelessly. The Emerald comes standard with 4 independent outputs and a TCXO 280ppb oscillator. The resolution and accuracy of the width, delays, and period counters is improved over previous instruments and allows for finer adjustments and more precise synchronization. This model also features virtual channels adding 4 "virtual" channels which effectively double the number of channel timers the unit may utilize and a "Period Counter" which measures the time between incoming external trigger pulses. The Emerald also offers an optional (TZ50), for driving 50 ohm loads & adjustable output module. With intuitive, streamlined GUI control of timing parameters and quick recall of up to 6 system configurations, the instrument is instantly ready for use. Complete control of the Emerald is provided through the standard USB interface or optional Bluetooth connectivity.
